The potential of [L 2 Pd(2,2′‐bpz‐ N 1 , N 1′ )] 2+ [L 2 = en ( 1 ), L = H 2 O ( 4a ), 2,2′‐bpz = 2,2′‐bipyrazine] for use as an angular element in the generation of self‐organized systems of variable molecular architecture has been studied. Ag + forms an infinite loop 3 with 1 , in which the metal ions function as cross‐linking agents between the organic entities 2,2′‐bpz. Complex 4a , on the other hand, self‐assembles as a bis(μ‐OH) dinuclear species 4b , and in the presence of 4,4′‐bipyridine (4,4′‐bpy) as a molecular square 6 with the heteroaromatic 4,4′‐bpy ligands representing the cross‐linking entities.
